Disable Automatic Host Registration in the vSphere Web Client

<

When you use EMC CLARiiON or Invista arrays for storage, it is required that the hosts register with the arrays. ESXi performs automatic host registration by sending the host's name and IP address to the array. If you prefer to perform manual registration using storage management software, disable the ESXi auto-registration feature.

Procedure

Browse to the host in the vSphere Web Client navigator.

Click the Manage tab, and click Settings.

Under System, click Advanced System Settings.

Under Advanced System Settings, select the Disk.EnableNaviReg parameter and click the Edit icon.
